Abstract

PURPOSE:To polish a card clothing uniformly by supporting a grinding wheel pivoted to a guide shaft with free rotation and reciprocating motion on one side and supporting the central part of a frame equipped with a drive unit via rotatable steel balls also with free reciprocating motion, on the other side, by means of a supporter. CONSTITUTION:The frame 5 of a card clothing polishing device is supported in reciprocating motion by a supporter 11 via steel balls 8 rotatably arranged in a plurality of hollow sphere caps 9 respectively, while its tip being guided to a guide shaft 1 by means of a bearing 3, further a grinding wheel 2 being rotatably pivoted on the bearing 3 via another bearing. Further, a motor 6 is arranged on the other end of the frame 5 to drive the grinding wheel 2 in rotation via a belt 7 so that the grinding wheel 2 makes reciprocating motion on the supporter 11 by being guided to the guide shaft 1 by means of a timing belt 12 so as to polish a needle cloth 16 confronting it. Since the grinding wheel 2 section and a driving unit 6 are put in mutual balancing in this way, the movement of the grinding wheel 2 can be carried out smoothy because of no eccentric load applied to the guide shaft 1, thus the card clothing 16 can be polished uniformly, accurately and quickly in a card machine.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to card machine elastic clothing (usually abbreviated as F, C1C) and metal side 1IH5 (usually abbreviated as M, C1C). The present invention relates to an all-in-one cloth polishing device for use in a card machine for polishing materials such as materials.

(Prior Art) The clothing polishing device used in the conventional Kerr I-machine is of the long roller type, in which Sun I vapor is wound around a shaft and rotated to polish the clothing.

Furthermore, there is a hollow hose roller system in which a part of the long-sleeved body is rotated along its axis as a grindstone, but is this system suitable for polishing four cloths made of carbon steel? , from the point of view of the structure, such as being a part of the whetstone part,
In this case, the number of rotations is approximately 40 ORPM, which means that the circumferential speed of the grindstone is slow, and since the roller is long, it tends to swing easily when rotated at high speed. In addition, the grinding wheel and the drive device are attached to the head for horizontal movement, and the method that has recently been used in some cases is that the load is applied to the part of the head and the spatula bends, making it difficult to polish. It is difficult to achieve high precision, and increasing the precision of polishing requires high costs.
There are various drawbacks such as overall weight and size.

(Problems to be Solved by the Invention) Therefore, the present invention eliminates the drawbacks of the various methods in the prior art and provides a structure that allows the circumferential speed of the grinding wheel to be suitable for grinding clothing made of carbon steel. It was created for the purpose of developing a polishing device for card machines that has high polishing accuracy, can be polished quickly and uniformly, and is light in overall weight.

(Another Means to Solve the Problems) In other words, in order to achieve the above-mentioned object, the present invention includes a guide shaft, a guide shaft that rotates about the guide shaft as a pivot, and moves in the axial direction of the guide shaft. A grinding wheel for polishing cloth, a rotational drive device for the grinding wheel, a support supporting the center of gravity of the entire grinding wheel and rotational drive device, and a movement of the entire grinding wheel and rotational drive device in the axial direction of the guide shaft. This is a polishing device for clothing that is fed into a card machine, and includes a moving device for moving the cloth.

Note that the term "card" here includes flat cards, roller cards, and clothing has a cartink effect, so there are several words written on the card, including elastic clothing (F, C, C) and metal. It refers to the side cloth (M, C, C').

(Function) The present invention constituted by the above-mentioned means supports substantially the center of gravity of the rotating grinding wheel and its rotational drive device as a whole by the support.
Almost no load is applied to the guide shaft.

Therefore, even if the guide shaft becomes long or the amount of lateral movement is large, the guide shaft will not bend due to the load, and in conjunction with the high speed rotation of the grinding wheel, the accuracy of the clothing can be improved. It allows for good, uniform and quick polishing, and it also makes the entire polishing device lighter.

(Example) In order to further clarify the gist of the present invention, the following will continue:
DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a clothing polishing device installed in a car machine according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, a grinding wheel 2 rotates around a fixed guide shaft 1. This grinding wheel 2 and guide shaft 1
The mating is done by double rolling bearings. The inner rolling bearing 3 is provided with a linear hair link for movement in the axial direction of the grinding wheel 2 or the guide shaft l. Next, the outer rolling bearing 4
is a bearing for rotating the grinding wheel 2 or the guide shaft l as the rotation axis. Therefore, the outer ring of the bearing 3 is fixed to the frame 5 with a bolt 20, and the inner ring of the bearing 4 is fitted to the outer ring of the bearing 3. Note that the bearing 4 is provided with an oil seal 21.

Next, the grinding wheel 2 is rotated via the motor 6 or the belt 7. At this time, the rotation speed of the grinding wheel 2 is 1°500 to 2.5°.
It is 50ORPM. The motor 6 is fixed to the frame 5 through a bolt 22.

Further, two steel balls 8 are arranged approximately at the center of gravity of the grinding wheel 2, the bearings 3 and 4, the motor 6, the gear wheels 1-7, and the frame 5 as a whole.

The steel ball 8 slides on the inner wall of the hollow ball crown 9 and rotates freely. And a holding part 10 formed with two hollow spherical crowns 9.
is fixed to the frame 5 by pins 1 to 23 and nuts 24. The steel ball 8 is a rectangular tubular support 1], -,
Located at I=. In this case, since the guide shaft 1 and the support body 11 are arranged parallel to each other, even if the steel ball 1 is moved in the axial direction of the guide shaft 1 by being pulled by the frame 5 or the timing heald 12, the steel balls 8
It will not come off from the support 11''.

In addition, the timing hold 12 is Holt 23 and Nats 2.
4 is fixed to the frame 5. In this way, since the approximate center of gravity of the entire apparatus is supported by the support 11, the guide shaft 1 is well-balanced with this pivot point at 7 m, and almost no load is applied to the guide shaft 1. Also, since the clearance of the bearing 3 is a near-hair link, it is necessary to make it as small as possible, so the movement of the guide 1 of the grinding wheel 2 in the axial direction can be made smooth.

Next, FIG. 4 shows an explanatory view of the main part of the operation of the above embodiment, and both ends of the timing helmets 1 to 12 are fixed to the frame 5 as described above. This timing hold 1
As shown in FIG. 3, reference numeral 2 has a toothed heald, and when the driving wheel 13 is rotated by a motor (not shown), the timing heald 12 moves and the frame 5 moves in the axial direction of the guide shaft 1.

At this time, the driven wheel 14 only rotates as the timing heald 12 moves.

Note that the driving wheel 13 and the driven wheel 14 are geared and mesh with the teeth of the timing belt 12.

In this way, as shown in FIG.
The needle tip 16 of No. 5 is ground by the grinding wheel 2. In addition, plan 1 cloth 1
5 is fixed to the surface of the cylinder 17 as shown in the figure. By rotating the cylinder 17 about its axis, the gold tip 16 provided on the entire circumferential surface of the clothing 15 is polished.

It should be noted that this embodiment describes only one embodiment of the present invention, or may be arbitrarily defined within the scope of achieving the above-mentioned purpose and operation of the present invention and the effects described below, and these changes are not subject to change. It goes without saying that none of these changes the gist of the present invention.

(Effects of the Invention) As described in detail above, the present invention provides a rotatable steel ball in the center of the frame, makes it contact with a support body to enable reciprocating movement, and has a guide shaft on one side. A grinding wheel is pivotally supported so that it can freely rotate and reciprocate, and a drive device serving as a drive source for the grinding wheel is disposed on the other side.Therefore, the grinding wheel portion and the drive device are balanced using the support as a pivot point. Because I configured it by letting
Since no biased load is applied to the guide shaft, the rotating grindstone can move smoothly in the axial direction of the guide shaft, and therefore, the clothing in the card machine can be polished uniformly, accurately, and quickly.

Next, since the grinding wheel can be moved in the axial direction of the guide shaft, there is no need to increase the length of the grinding wheel in the axial direction. Therefore, it is possible to increase the rotational speed of the grinding wheel, or to set it to a rotational speed suitable for polishing the clothing. Furthermore, since the speed is extremely high compared to the conventional long roller method and hose roller method, the polishing time is significantly reduced and the accuracy of the polished surface is greatly improved. This invention can be said to be of great practical benefit, since it is possible to obtain a polished surface with high precision, even though the surface is not uniform, and it has great economical effects.
